WINDOW-CLEANER.

Specification of Letters Patent.

Application led April 8, 1915. Serial No. 20,086.

To all LU/wm t may concern.'

Be it known that l, ODIN G. CLAY, a citi- ,zen of the United States,residing at Washington, in the District of Columbia, have invented a newand useful Window-Cleaner, of which the following is a specification.

The device forming the subject matter of this application is' adapted tobe employed for removing frost, moisture and the like 'from the windowpanes of vehicles.

@ne object of the present invention is to providenovel means for movinglongitudinally of the window pane which is to be cleaned, a travelerwhich carries means for cleaning the pane. Y

Another' object of the invention is to provide novel means whereby ascraper carrier may be moved transversely of the plane dey'fined by thewindow pane, as the traveler on which the scraper carrier is mountedmoves longitudinally of the pane.

Another object of the invention is to provide a combined means formoving the traveler andthe scraper carrier longitudinally of the paneand .for advancing the scraper carrier toward the pane.

t is within the province of the disclosure to improve generally and toenhance the dit .dil

utility of devices of that type to which the present inventionappertains.

l/Vith the above and other objects in view .which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

InV the accompanying drawings :-Figure 1 is an end elevation of avehicle whereunto the device forming the subject matter or l thisapplication has been attached; Fig. 2

is a fragmental vertical section;` Fig. 3 is a fragmental horizontalsection; Fig. 4f is a rear elevation showing a portion of the travelerand parts carried thereby, certain elements being shown in section.

ln the accompanying drawings the nu meral 1 indicates a supportingstructure, such as a car, provided with a sash frame 2 carrying a pane3. Brackets 4 are attached -to the car l above the window frame 2 and inthe brackets 4 is carried a spring actuated roller 5 which may beconstructed like an ordinary Hartshorn curtain roller, or in any otherdesired manner.

The invention comprises a traveler 6 in the form of a rod or bar mountedtomove vertically in a direction parallel to the sash frame 3. At itsends, the traveler 6 is equipped with transverse heads 7 carryinganti-friction means such as wheels 8, adapted t0 move in tracks 9 formedin the frame work of the car l. The upper ends of primary fiexibleelements l()y which may be tapes, are secured to the roller 5 and arewound about the roller. The depending ends of the flexible elements 10are attached to the traveler 6.

The invention comprises a scraper carrier l1 mounted to move verticallyalong with the traveler G and to move horizontally, that is,transversely of the window pane 3. The scrapercarrier which is denotedby the numeral l1, preferably is in the form of a bar and assembledtherewith are sup orting elements 12 which may be screws, the supportingelements 12 being slidably mounted in the traveler 6 for horizontalmovement.

'Compression springs 14 of considerable strength are interposed betweenthe heads of the shpporting elementsl 12 and the traveler G. The carrier1l is provided with a pair of superposed Scrapers l5 which may beresilient strips of rubber or other suitable material. The scrapers 15are applied to the upper and lower edges of the carrier l1 and are heldthereon by means of clips 16 in the form of strips, the clips 16 beingretained on the carrier l1 bymeans of securing elements 17.

The invention comprises a pair of actuating members 18 in the form ofwedges, each comprisinga head 19 and a shank 20, the

forward and rear faces of the shanks 2O preferably being parallel. Theactuating members or wedges 18 are mounted to move vertically in notchesor seats 28 formed, as shown best in Fig. 3, in the traveler in thecarrier 11 and in the uppermost securing strip 1G. Ilhe actuatingmembers 1S are providedV with vertically elongated slots 29 whereby` theactuating members are mounted to slide on the supporting elementsorvscrews 12.

Secondary flexible elements 21 are connected to thc lower ends of theactuating members 1S and extend downwardly through openings 22 in thewindow sill 25, around idlers 23, upwardly through openings 24 in thesill, across the'roller 5, if desired,

in the 'present instance shown in the formA of rings. As clearly. shownin Fig. 2, the handles 27 abut against the frame work of the car tolimit the movementof the traveler 6 in one direction, under the actionof the spring ldriven roller 5. 4

In practical operation, the flexible elements 21 are drawn over theidlers 22 and move rearwardly at their upper ends, when a pull isexerted on the handles 27. By this operation, thetraveler 6 is caused tomove downwardly, the flexible elements 10 being unreeled from the roller5 and the springs thereof being put under tension. 'As .the traveler (3is moved downwardly due to the pull exerted by the flexible elements 21on the wedges 18, the wedges act transversely against the carrier 11 andmove the same toward the window pane 3. Thus,fthe scrapers 15 arepressed firmly against the window pane 3. So soon as the handles 27 arereleased, the spring driven roller 5 reacts on the flexible elements 10vand draws the traveler 6 upwardly. The springs 14; react on thesupporting elements 12 and pull "the carrier 11 forwardly, and since thebeveled heads 19 of the actuating members or wedges 18 are inclined, theactuating members will rise under the action of the springs 14 andassume again the positions of Fig. 2, the Scrapers 15 thus being movedforwardly Y so that they coperate with the forward face of the upperrail of the sash frame 2.

Having thus described the invention, what is claimed is:

1. In a window cleaner, a traveler mounted to reciprocate in one plane;a scraper carrier mounted to reciprocate on the traveler toward and fromscraping position at an angle to the plane in which the travelerreciprocates';l a wedge movably interposed between the carrier and thetraveler and constituting means for advancing the carrier to scrapingposition when the wedge and the traveler are moved in one direction;

means assembled with the wedge for moving carrier mounted to reciprocateon the traveler toward and from scraping position at an angle to theplane in which the traveler reciprocates; a Wedge movably interposedbetween the carrier and the traveler and constituting means foradvancing the carrier to scraping position when the wedge and thetraveler are moved in one direction; means assembled with the wedge formoving the wedge and the traveler in said direction; means for movingthe traveler in an opposite direction; and a resilient connectionbetween the traveler and the carrier, whereby ythe traveler and thecarrier will be drawn together, thereby to move the wedge on the carrierand the traveler in the last specified direction.

3. In a window cleaner, a traveler mounted to reciprocatein one plane; ascraper eler toward and away from scraping po-v sition at an angleto theplane in which the traveler reciprocates; a movable actuating elementinterposed between the carrier and the traveler and constituting meansfor advancing the carrier to scraping position when the actuatingelement and the traveler are moved in one direction; means assembleddirectly with the actuating element for moving the actuating elementindependently of the traveler, the actuating element subsequentlycoacting with the traveler to move the same in said direction; and meansfor moving the traveler in an opposite direction.

In testimony that I. claim the foregoing as my own, I have heretoaffixed my signature in the presence of two witnesses.
